John Gill Commentary Acts 23:28

"And desiring to know the cause wherefore they accused him, I brought him down unto their council:" — Acts 23:28 (ASV)

And when I would have known the cause
Or crime, he was guilty of:

wherefore they accused him :
which they charged him with, and for which they beat him almost to death:

I brought him forth into their council ;
their court of judicature, the great sanhedrim.
